LNR1H334MSEN

The LNR1H334MSEN is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNR series, designed for general‑purpose power applications requiring large bulk capacitance and high ripple handling. It combines a 330000 µF capacitance at 50 V with a robust screw‑terminal can package (φ90 × 170 mm) for secure mounting and high current connections.

With high rated ripple currents, a broad operating temperature range of −40°C to +85°C and a 5000‑hour endurance at 85°C, this part is targeted at industrial and power electronics designs that need energy storage, DC smoothing and reliable long‑term operation under continuous load.

Key Features

• High Capacitance & Voltage: 330000 µF at 50 V provides substantial bulk energy storage for smoothing and decoupling in power systems.
• High Ripple Current Capability: Rated ripple current of 25.3 A at 120 Hz and 29.09 A at 100 kHz to support high‑load and switching applications.
• Screw Terminal Mounting: Radial can with screw terminals enables secure, low‑resistance connections for high current paths and easy installation in rack or chassis assemblies.
• Endurance and Temperature Range: 5000 hours lifetime at 85°C and an operating temperature range of −40°C to +85°C for sustained thermal reliability.
• Electrical Characteristics: Polarized capacitor with ±20% capacitance tolerance and specified leakage current of 5000 µA; tan δ specified at 0.75 (measurement per series datasheet conditions).
• Mechanical Size: Body dimension φ90 × 170 mm (L: 17 × D: 9 cm) suitable for high‑energy density power modules and cabinet installations.
• Packaging & Production: Supplied in cardboard packing and available in mass production quantities for volume applications.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and energy storage for large DC power supplies and converters that require sustained ripple handling and capacitance.
• Inverters and Motor Drives: DC link and smoothing capacitor for power conversion stages where high ripple currents and robust mounting are required.
• Backup Power & UPS Systems: Energy reservoir and smoothing in backup power systems to stabilize DC rails during transitions and load events.

Unique Advantages

• Substantial Energy Density: 330000 µF at 50 V provides large bulk capacitance to reduce the need for multiple smaller capacitors and simplify BOM.
• High Current Handling: Elevated ripple current ratings at both low and high frequencies enable reliable performance with switching converters and high‑load circuits.
• Robust, Serviceable Termination: Screw terminal design allows secure electrical and mechanical connections that are easy to service during assembly or maintenance.
• Designed for Long Endurance: 5000 hours at 85°C endurance specification with defined limits on capacitance change and leakage supports predictable lifetime planning.
• Wide Operating Range: −40°C to +85°C operation covers a broad set of industrial environments where temperature resilience is required.
